clang: fix tooltip missing closing bracket with default argument calls
To easily reproduce the error if present with the clang used, simply add a declaration of a method with default arg values and wait until the parser has added the info to the DUChain, then hover:
void foo(const QString& a = QString(), const QString& b = QString());
The ")" from "= QString()" can be missing in the tooltip without this patch.
